A man wielding a knife attacked students Friday at a school in central China, leaving 22 children and one adult injured, according to state-run media reports.

The attack occurred at the gate of an elementary school in the village of Chengping, in Henan Province. Police arrested the attacker, who they identified as local resident Min Yingjun, 36.

Children as young as six were among those hospitalized after the attack, suffering injuries including slashes to the ears and head.

An official at Guangshan Traditional Chinese Medicine Hospital, the local facility, told CBS News at least two students had been transferred to the larger city of Wuhan, not far from Chengping, for treatment. The editor of the local newspaper which first reported the story said none of the children had injuries severe enough to threaten their lives.

Some Chinese bloggers have blamed the lack of freedom of expression for the attacks, suggesting people frustrated by their own circumstances but lacking the means to seek justice or voice their concerns with the all-powerful communist government, lash out instead at the least powerful members of society.
